have problems with 'em. Me included. But with time (it seems to vary among us) things do settle down. With me, when the thing started to really freak out, i hit the freezer for the ice packs, 15min on and 15 min off. It really settled thing down on the escalation of the spasm.

I heard once and i really believe it, that if one stands either straight or bent over that stresses in the back are better relieved if the feet are not side by side. In other words have one foot forward of the other, especially when lifting.
